Evening All,

Looking for some advice:

I recently upgraded my camera from a 183M to a 26M. But using the same EFW with 1.25" inch filters. This is with a "wave 80" scope (80mm aperture, f6 with a 0.8x reducer so 384mm focal length) 

Sensor to filter distance is 28.5mm.

I thought I might get away with it: according to the "CCD Filter Size" on astronomy.tools website which specifies a minimum filter size of 32mm (1.25" = 31.75mm) 

Attached is the integrated LUM channel and it's corresponding flat. (I might re-do the flats to see if anything has changed, I'm still in the "shake down" phase of the new camera I guess......)

Or maybe it's something else altogether? I haven't attached the heater yet but it wasn't a cold or humid night

.

Opinions welcome, thanks in advance!
 

 

Looks like it's vignetteing due to the 1.25 inch filter, that's my opinion other's my have some other explanation 🤔

Thanks and well figured out from my vague post

 

Yes Milkyway bortle 3 mostly

You will only need a IR/UV filter if you have had your DSLR full spectrum modified 

Thanks that will do for me🤗👏

Oddly that is how it's been here in Spain over the past months. Maybe there is an explanation?

So in my infinite wisdom I made a cap with a hole in it to put on the front of my scope. My thinking behind this was I’d be able to use the little dot of light sort of like an artificial star so I could get my focus tube nice and concentric. But all I succeeded in doing was making a very expensive pinhole camera 😂😂

 

Wondering what the focal ratio was if it was on your scope 🤔

It wouldn't suprise me if the very first response they got was enough to put the OP off ever visiting here again.  

Too right totally out of order!

Clouds 🤬

Is it available to fit a Canon 750D🤔😵‍💫

Really unless you are willing to travel to a dark site we are stuck with whatever Bortel we have, whether it's 2 or 8.

Second image certainly put a new slant on it , I like it, I always say if you are happy with a image then it's ok, and to me it's ok🤗

What a great image beautiful detail,your right to be happy with the result 👏👏

Thanks for all the detail @woldsman That's really useful. I think the last piece of the puzzle is polar aligment and think I might try the electronic method using NINA first and see how I get on.

I have the NINA plug in and everything else, there's a few options here like syncing Stellarium and NINA as you say. 

Figers crossed there are some clear skies soon. Maybe even this weekend,

This may be of interest to you regarding polar alignment, I use pole master it gets you aligned very accurately,once I have done it I am aligned and have never needed to re align ,but I check it every 6 months . My rig is permanently set up, yours might be but it doesn't take long with pole master if it's not.

Hey folks - Bruce J Richmond, VA - There's probably a post somewhere about this but I'd like to control my Meade LX 90 from inside the house which means a camera and whatever cabling is necessary to accomplish this - If one of you nice folks could point me in the right direction I'd really appreciate it.

BTW the scope has 2 AUX ports on it and my laptop just has USB ports and a HDMI port.

Great to be part of this group - Thanks for your time,  

Hi I have the same scope ,the way I did it was to buy a 10 mtr cable for the hand control ran this into the house , at the time I was using a Canon DSLR linked to my laptop with live view I could see the object I was imagining.This is the easiest way 📷👍

What a great image and you got detail in M31  plus that reflection of the comet in the lake . Outstanding 👍🌠

Hi this is a DSLR cooler I made, it makes quite a difference in the summer nights

Why people pay 30 quid for 3 screws is beyond me.  Like any hobby, we get ripped off if people dont know any better

Quantity 10  M4 x30mm screws here for 9 quid.

You're welcome 🙂

Your right I've found I can always find what I need from other sources and save money 🤗

I am experimenting with a custom TEC cooling and a bit worried about my mount electronics. The Peltiers will operate at ~14V, so far the plan is just to hook them up on the same splitter where the HEQ5 is connected. Can I go wrong with that?

I have a cooler for my DSLR which I only use with separate power supply.

Greatly appreciate the responses. This all makes sense. Yes the lens is in great shape. I am not removing it to replace it. As to why, that would derail this thread terribly! I will post my results when I have found another person to assist with grabbing the tube.

Thanks again!

 

Sounds interesting 🤔

Thanks folks. I’m sure the sensor is dusty, so I’ve ordered a cleaning kit.

Take your time only use cleaning pad for one pass ,then use a second one.As said use blower first before you clean 

I think its a great image green star or not, nothing wrong with a bit of colour variety

The way I reconcile this is -  because we (our intellect) are part of existence (ourselves products of the "after the big bang") we are constrained only to know that existence or reality. The common answer is that anything prior to that is not a legitimate question as prior is a measure of time and time appears to be a property of existence (part of the fabric of our universe).  That leads to the entirely unsatisfactory "time",  and hence "prior", did not exist before the big bang.  That's so difficult for us to conceive because we don't experience time like that so our thinking is constrained.  

But as you say "hats off to them" - it's one thing to read about it, another to come up with it from first principles. They are genuinely gifted people.

Time is a measurement created by we humans,it is our way of understanding and explaining things around us including distance,if we were not here time would go on but unmeasurable 

Looks like a dust moat, your sensor needs a clean you can get a cleaning kit from a camera shop.
